Vocalizations of wild West Indian manatee vary across subspecies and geographic location
Scientific Reports, 2023 Geographic variation in the vocal behavior of manatees has been reported but is largely unexplored. Vocalizations of wild West Indian manatees (Trichechus manatus) were recorded with hydrophones in Florida from Florida manatees (Trichechus manatus ...

Using transfer learning with a convolutional neural network to detect African manatee (Trichechus senegalensis) vocalizations [PDF]
JASA Express Letters, 2022 African manatees (Trichechus senegalensis) are vulnerable, understudied, and difficult to detect. Areas where African manatees are found were acoustically sampled and deep learning techniques were used to develop the first African manatee vocalization ...

Chronic exposure to glyphosate in Florida manatee
Environment International, 2021 Florida manatees depend on freshwater environments as a source of drinking water and as warm-water refuges. These freshwater environments are in direct contact with human activities where glyphosate-based herbicides are being used. Glyphosate is the most

Scholarpedia, 2009 Tactile hairs function to detect mechanosensory stimuli rather than for warmth or protection, which is the main function of pelage hair. Vibrissae, which have a specific set of structural features, are the main class of tactile hair.

Manatees display diel trends in acoustic activity at two microhabitats in Belize.
PLoS ONE, 2023 Many marine mammals exhibit diel trends in vocal production, which can provide information on habitat use and behavioral activity. In Belize, Antillean manatees (Trichechus manatus manatus) commonly inhabit small depressions in the substrate or deep ...

Macro-habitat preferences by the African manatee and crocodiles – ecological and conservation implications [PDF]
Web Ecology, 2012 African manatees (<i>Trichechus senegalensis</i>) and crocodiles are threatened species in parts of their range. In West Africa, crocodiles may constitute the main predators for manatees apart from humans.

Environmental characterization of home range of Antillean manatees (Trichechus manatus) released in northeastern Brazil [PDF]
Anais da Academia Brasileira de Ciências, 2023 The Antillean manatee occurs discontinuously from the state of Amapá to the state of Alagoas on the coast of Brazil. There is also evidence of reintroduced manatees using the coasts of Sergipe and Bahia, with a preference for calm shallow waters.

Health assessment and seroepidemiologic survey of potential pathogens in wild Antillean manatees (Trichechus manatus manatus). [PDF]
PLoS ONE, 2012 The Antillean manatee (Trichechus manatus manatus), a subspecies of the West Indian manatee, inhabits fresh, brackish, and warm coastal waters distributed along the eastern border of Central America, the northern coast of South America, and throughout ...
